Reflection: Developing a Conceptual Understanding Subtracting from 8 - Section 2: Presentation of Lesson


Throughout school, I remember my teachers telling us not to use our fingers.  Using your fingers to solve a problem was basically as bad as cheating!  I think that in kindergarten fingers can be students best manipulatives.  Now I want to explain that a bit.  I think that there are other ways to solve problems, sometimes better ways, but when a student doesn't have cubes, counters, a number line or even a piece of paper and pencil, they always have their fingers.  I want my students to know that using their fingers is an option.  The caution with this is when developing fluency.  At this point we are just learning how to subtract.  My students need strategies to solve these problems.  As we develop fluency, the use of fingers disappears.

Objective: Students will be to able solve subtraction equations.

Big Idea: We have 10 fingers, so when learning to subtract starting with a number less than 10 or equal to 10, students can use their fingers to help them. Manipulatives and drawings are helpful too!
